Weight-loaded safety valves use a counterweight mechanism to activate pressure relief in the system. They are intended for simple steam and process applications where reliable overpressure protection is required without the use of a spring mechanism.
- Design: weight-loaded valve (direct loading)
- Activation: mechanical, using a counterweight
- Testing standard: EN 12266 / DIN 3230
- Pressure rating: PN 16
- Media: steam and process gases
- Adjustment: set by counterweight position
- Industrial application
